Development of the Soil Macrofauna Community under Silvopastoral and Agrosilvicultural Systems in AmazoniaBackgroundThis study seeks to analyze the effect that different agroforestry systems have on the recolonization of macrofauna in the soil of former pasture lands.

Establishment of Tree Seedlings in the Understory of Restoration Plantations: Natural Regeneration and Enrichment PlantingsBackgroundThis study investigates how seedling establishment is affected in the understory of restoration sites of different ages (10,22 and 55 year-old) within the Brazilian Atlantic Forest. It also assesses some of the environmental microsite conditions that influenced the stand dynamics process. Available with subscription or purchase |
Variation in the Population Structure Between a Natural and a Human-Modified Forest for a Pioneer Tropical Tree Species not Restricted to Large GapsBackgroundThe study was conducted in a permanent plot in a primary forest at Caetetus Ecological Station (CES), and in an early successional forest adjacent to the state reserve at Torrão de Ouro Farm, state of São Paulo, Southeast Brazil. This forest originally covered nearly the entire plateau in the state of São Paulo, and it is currently the most threatened forest in the State due to past fragmentation. Open access copy available |
Effects of Logging, Liana Tangles and Pasture on Seed Fate of Dry Forest Tree Species in Central BrazilBackgroundThis article examines seed germination, predation, removal, and death for six different species in undistured forest, logged forest and an active pature. Because gaps created from logging are often overrun by liana tangles, it also compares seeds planted under patches of lianas (low forest) and seeds under patches of mature forest (high forest).

Methodology for Comparative Analysis of Sustainability in Agroforestry SystemsbackgroundThis paper analyses different forms of agroforestry systems, including political and institutional linkages in the Caí and Taquari river valleys of the Brazilian state of Rio Grande do Sul in an effort to determine their sustainability.

Intensive Silvopastoral Systems: Improving Sustainability and Efficiency in Cattle Ranching LandscapesBackgroundThe article summarizes productivity benefits from implementation of intensive silvo-pastoral systems (ISPS) in Colombia, Mexico and Brazil, including benefits for the well-being of cattle, heightened biodiversity, and decreased area needed for production (allowing for greater quantities of forest area). The authors also summarize challenges inhibting greater adoption of intensive silvo-pastoral systems, and potential policy solutions for overcoming these challenges. Open access copy available |

Neotropical Secondary Forest Succession: Changes in Structural and Functional CharacteristicsBackgroundThis paper reiviews the main biotic and abiotic factors that influence patterns of secondary forest succession in the Neotropics after complete forest clearance due to human activities. Research Goals & MethodsThe authors look at patterns of species replacement and various processes that occur during succession and suggest that the sequence of processes may be predictable even if species composition is not.

Ecosystem Restoration of Riparian Forests in Sao Paulo ProjectBackgroundSince the 1970s, the Sao Paulo region of Brazil has experienced extensive expansion of the agro-industry, reducing native vegetation coverage, increasing strain on natural resources, and contributing to land degredation. The Ecosystem Restoration of Riparian Forests in Sao Paulo Project was created in 2005 and ran until 2011 to correct these trends. Open access copy available |
Tropical rainforest regeneration in an area degraded by mining in Mato Grosso State, BrazilBackgroundGold mining has been a major cause of environmental degradation in the rainforests in the north of Mato Grosso State, Brazil. Regulations on mining activity are beginning to be developed, including standards for forest recovery methodologies. This study characterizes natural tropical rainforest regeneration in Matupa County, Mato Grosso State, Brazil. Open access copy available |
